I attached an image of what i am trying to do in my original post.

Anyway, using the IP from the DMZ server to the WP1 & WP2 have no difference in speed. WP1 loads fine, WP2 loads very slow

Ping the IP Addresses from your work station, check that they are around the same.
Ping the URL for each and look for obvious differences to the IP Address pings.
Run a traceroute from each and look for differences.
Check and make sure that the reverse lookup is the same.

You could also look at things like the network config, between the switches if they are physically different.

It would also be worth looking at the /etc/network/interfaces file on the proxy.

There are just so many possibilities here, it will have to be a process of elimination.

ping & traceroute blocked between networks here, sorry.

Network A these servers are all VMs and on the same subnet.

I'd just like to know what you use for user account management on your DMZ servers? Do you use the same authentication realm as internally? Do you use a different authentication realm, perhaps only for the DMZ? Do you use local accounts?

rping

RPING(1)							     librdmacm								  RPING(1)

NAME

       rping - RDMA CM connection and RDMA ping-pong test.

SYNOPSIS

       rping -s [-v] [-V] [-d] [-P] [-a address] [-p port]
		 [-C message_count] [-S message_size]
       rping -c [-v] [-V] [-d] -a address [-p port]
		 [-C message_count] [-S message_size]

DESCRIPTION

       Establishes  a  reliable  RDMA connection between two nodes using the librdmacm, optionally performs RDMA transfers between the nodes, then
       disconnects.

OPTIONS

       -s     Run as the server.

       -c     Run as the client.

       -a address
	      On the server, specifies the network address to bind the connection to.  On the client, specifies the server address to connect to.

       -p     Port number for listening server.

       -v     Display ping data.

       -V     Validate ping data.

       -d     Display debug information.

       -C message_count
	      The number of messages to transfer over each connection.	(default infinite)

       -S message_size
	      The size of each message transferred, in bytes.  (default 100)

       -P     Run the server in persistent mode.  This allows multiple rping clients to connect to a single server instance. The server  will  run
	      until killed.

NOTES

       Because	this  test maps RDMA resources to userspace, users must ensure that they have available system resources and permissions.  See the
       libibverbs README file for additional details.
